The invention discloses a power transmission line dangerous point on-site auxiliary management and control technical prevention device. The device comprises a high-voltage near-electricity anti-touchdetection terminal, a high-voltage sensing circuit and a wireless transmitting circuit, wherein the high-voltage near-electricity anti-touch detection terminal comprises a waterproof box, and the high-voltage sensing circuit and the wireless transmitting circuit are arranged in the waterproof box; the high-voltage induction circuit is connected with an induction antenna extending out of the waterproof box, the wireless transmitting circuit is connected with a communication antenna extending out of the waterproof box, the high-voltage induction circuit is used for inducting high voltage of 220V or above, and the wireless transmitting circuit transmits a wireless early warning signal to the intelligent early warning host after the high-voltage induction circuit inducts the high voltage; theintelligent early warning host is provided with a wireless receiving circuit and an alarm, the wireless receiving circuit is used for receiving the early warning signal sent by the wireless sending circuit, and after the early warning signal is received, the alarm sends out an early warning. According to the device, early warning is carried out in time when aerial work equipment approaches a livewire, and a safety distance between engineering operators and vehicles is ensured.
Description
technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to electric power safety protection technology. Background technique [0002] At present, various large-scale machinery (such as cranes) are frequently under construction in the transmission line protection area. Due to the wide distribution of high-voltage transmission lines, it is inevitable that various large-scale machinery must be hoisted under high-voltage transmission lines. When lifting, it is difficult for the driver to judge the distance between the crane arm and the high-voltage line according to the naked eye. Electric shock casualties and large-scale power outages. Contents of the invention [0003] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide an on-site auxiliary management and control technical prevention device for the dangerous point of the transmission line...
